Be it known that ,I, J nnmin u pnoniit, f acitizen of the United States,residing at and State of (jhio, have invented certain new and usefulImprovementsin Tools for 5 .Wires on High-Voltage Gir- 1 cuits, of whichthe following is a specifiwire in contact with the stem 1, carr ing acation. w 0 This invention relates more particularly to a special tooldesigned for use in manipulating insulator tie-wires on high potentialtransmission lines, while the power 18 on the. line.

According to the commonly prevailing practice, the danger to theworkmen, due to the high voltage carried, is too great to permit 0changing or manipulating such tie-wires while the ower is on thecircuit, thus necessitatin either waiting until the power is shut o inthe ordinary course ofevents, as at night, or shutting down the powerand stopping trafiic and other operations dependent on the line. For thepurpose of overcoming these. difficulties, I have devised a novel formof tie-wire which may be wrapped around the power wire or unwrappedtherefrom, while the ower is on the circuit. For the purposeofmanipulating this improved tie-wlre, as well as for the purpose ofremoving an old type of tiewire, with perfect safety to the workmen, I

have devised the tool constituting the subject of the presentapplication.

In order to more fully describe this invention, reference will be hadto'the accompanying drawing, wherein- I F1 ure 1 represents aperspective view of one Eorm of my improved tool; Fig. 2 is a sideelevation thereof, partly in section; and Fig. 3 is a perspective viewshowing the said tool in operation as manipulating an insulatingtie-wire. 1

In the drawing, this tool comprises among other parts, a stem 1 whichmay be of metal or any other desired material, held at one end, by beingscrewed thereinto, or in any other suitable way, rigidly in an insulator2, preferably of the high otential petticoat type. This insulator may beone of the usual commercial insulators of this t pe, in the upper end of-which is bored a ole 3 to receive the stem 1. The insulator 2 iscarried by a. rod or handle 4, the upper end of which is specimens-b1Letters 'toi'Z'in-"t Wapakoneta, 'in the countyof Auglaize; 7

I For the purpose of pulling or pushing operations 1n coiling oruncolling my improved tie-wire, around or from the power conductor, thestem of this tool is provided with a plurality of spurs 5, 6, 7 and 8,the spur 5 slanting in the direction away from t e operator, While theother spurs slant in an' opposite direction, the former spurbeingemployed for pushing a wire away from the operator, while thelatter spurs are for the purpose of pulling the wire toward theoperator. 7

In Fig. 3, I have shown this tool in the act of operation in connectionwith my im-- proved tie-wire above referred to, wherein the tool isshown in the act of wrapping one of the ends of the tie-wire around thepower wire, the spur 6 being atthis time, in use to pull the loop 9 ofthe tie-wire toward the When he has pulled this loop toward him as faras possible with the tool, he then pushes it in the opposite directionby placing the spur 5 against the loop. He then pulls the loop towardhim again, by means of the spur 6 and by repeating this operation, wrapsthe tie-wire 10 around the stat- Patented Nov.26,-1912.

power-wire 11, as indicated.' The spurs 7 and 8 are merely for thepurpose of manipulatingthe wire closer to the operator than would beconvenient by means of the spurs 5 and 6. Obviously, an other desirednumber and disposition o spurs may be arranged on the stem 1.

It often becomes necessary to untwist one of the old or commonly usedforms of tiewire, from the power wire, in making the repair, in whichone of my improved tiewires is substituted. This oldform of tiewire doesnot have loops at their ends. Therefore, for the purpose of taking holdof the ends of this old tie-wire and untwisting them from thepower-wire, my improved tool is provided w1thtwo or more openings 12 and13. By slipping the end of this old tie wire in either of theseopenings, it may be uncoiled orunwrapped from the power wire andinsulator.

For the purpose of removing small branches of trees, and other obstacleswhich may interfere with the manipulation of this tool, I provide thestem 1 with a saw 14, by

' which these obstacles may be readily removed.

While I have herein described this tool with special relation to its usein connection with the manipulation of tie-wires, it will be understoodthat the same is susceptible to various other uses in manipulatlng linewires on high potential transmission circuits.

Having thus fully described my invention, what I claim is:

l. A tool of the class described, comprising a stem having spursthereon, an insulator on which said stem is mounted, and a rod to whichsaid insulator is secured, the said insulator separating the said stemfrom said rod.

2. A tool of the class described, comprisin}: a stem having oppositelydirected spurs thereon, an insulator on which said stem is.

mounted, and a rod to which said insulator is secured, the saidinsulator separating the said stem from said rod.

3. A tool of the class described, comprising a stem having oppositelydirected spurs thereon, a high potential insulator of the petticoattype, on which said stem is mounted, and a rod to which said insulatoris secured, the said insulator separating the said stem from said rod.

4. A tool of the class described, comprising a stem having a pluralityof oppositely directed spurs thereon, one or more openings in the saidstem adapted to receive the ends of wires, a rodforming a handle forsaid tool, and a high voltage insulator interposed between said stem andhandle, substantially as described.

In testimony whereof I aflix my signature in. presence of two witnesses.
